CJC-1295 No DAC vs DAC: What Is the Drug Affinity Complex?
The “DAC” in the CJC-1295 no DAC vs DAC comparison refers to the Drug Affinity Complex — a chemical modification that binds covalently to serum albumin after injection, dramatically extending the peptide’s half-life. CJC-1295 with DAC has a half-life of approx

- The “DAC” in the CJC-1295 no DAC vs DAC comparison refers to the Drug Affinity Complex — a chemical modification that binds covalently to serum albumin after injection, dramatically extending the peptide’s half-life. CJC-1295 with DAC has a half-life of approximately 6-8 days because the albumin binding prevents rapid enzymatic degradation. CJC-1295 no DAC (also called Mod GRF 1-29 or Modified GRF) lacks this albumin-binding modification, giving it a half-life of approximately 30 minutes.
- This half-life difference is the single most important factor in the CJC-1295 no DAC vs DAC comparison. It determines everything that follows: dosing frequency, GH release pattern, side effect profile, and stacking compatibility.
